Convert DXF to Gerber, and then I noticed small gaps in the traces when performing a DFM Check.

Thanks for sending the sample screen captures. The small gaps in the traces are causing the issue (with DFM, etc.). To resolve these small Gaps, please try the following:
1. Merge all adjacent polygons together. (A) Select all metal objects on Top and Bottom layers. (B) Go to menu: Tools / Convert To / Polygon... This will merge all adjacent polygons - thus removing the Gaps. Netlist extraction and DFM Checks will run smoothly afterwards. or 2. During DXF Import, check this option for the Polylines on your Metal layer. https://numericalsoftware-update.s3.amazonaws.com/tutorials/2016-01-11_5-53-58.pdf
